That didn't work for me.
My RTLC has the BMW audio unit. Nav5 works ok - or at least as well as a Nav5 ever will. Had a loaner RTLC with no audio recently. Tried to use the mp3 player in the Nav5 but got the error message "use bike audio system to list to music"
My 2014 RTLC did NOT have the BMW audio. I could listen to the MP3 tracks on the sd card in the Nav 5, Wonder wheel allowed me to change tracks and see what was playing, or change pages back to navigation and the other ones.. volume control on my bluetooth headset.
My new 2015 HAS audio, works fine. But I have not yet been able to have the BMW Audio working AND the Nav 5 instructions and phone. So far it's one or the other.
